Pagination/navigation issue in a Service type post, but not in a Page

Hello,
I’m experiencing a strange issue and I cannot find out why this is happening… I created a Service post, where I want to show a list of projects that have tags of that type of service. I found a nice plugin that works with that, post grid, it displays nice the projects with correct pagination if I “call” it from a Page, but inside the Service post the pagination does this: It shows the pages that it should have (1, 2, 3), the hrefs look that they send the request to the correct url (www.mysite.com/services/a_service/page/#number), but the page just reloads (it stays at www.mysite.com/services/a_service), where it was.
Is there anything at the theme that I could change to accept that pagination? It intrigues me the fact that is working fine in a page but not in posts…
Any help/ideas would be much appreciated.
Thank you a lot in advance.
